Fluid contamination is a significant concern in hydraulic and fluid systems, as contaminants in hydraulic, lubrication, or process fluids lead to equipment wear, corrosion and even catastrophic failures in sensitive equipment. Effective contamination control is essential for maintaining system reliability, optimizing performance and extending the life of both fluids and equipment. With advances in sensing, modelling and filtration technologies, industries are better equipped to manage fluid contamination and ensure system resilience. This paper presents the fluid contamination general aspects, main sources, the principal contaminants types, represented by different particles of solid contaminants (metallic fragments, dust and wear particles from machinery components) and its implications for system efficiency. The contaminant particles can be abrasive and cause wear on surfaces, water droplets often found in hydraulic and lubrication systems, leading to corrosion, degradation of additives and further reduced fluid operational performance, other air and gas particles entrained into hydraulic fluid volume leading to cavitation, reduced lubrication and oxidation. Main models describing the hydraulic fluid contamination are presented and further the numerical analysis results based on parameters primary considered for a hydraulic actuation type.
